PREFACE

This conference is held to disseminate current methods which provide advanced

materials and methods in pharmacy. This a good media for those who are engaged in

academic, industrial, regulatory fields to conduct social interactions, to share their

findings, to communicate bottle neck surrogates, and to seek the possibilities for

collaborations. Since it is our initial moment, we are quite humble to recognize our

weakness in running all agendas. Hence, from bottom of our heart we ask apologizes from

all participants for any service, lack facilities, low response, etc.. However, we must be

persistent and ensuring our positive contribution toward scientific society especially at

the attempt to develop capacity building of pharmaceutical sciences in Indonesia. Thus, we

will run ICB Pharmacy II in 2015/2016.

To all participants, I wish an inspiring moment in Solo city, a city where was born a

national leader and city of heritage !

Abstract

Generally, seed and stem of papaya (Carica papaya L.) are not used. In a previous study, seed and stem of papaya inhibit growth of Escherichia coli and Staphylococcus aureus. The aim of this study was to compare antibacterial activity of ethanolic extract of papaya seed to stem extract against Shigella dysenteriae and Streptococcus pyogenes. Papaya seed and stem were extracted using 70% ethanol by maceration method. The antibacterial activity tests were carried out using Kirby-Bauer disk diffusion method. Chemical compounds in the extracts were identified using thin layer chromatography (TLC) with silica GF254 asstationary phase and a mobile phase of ethyl acetate : methanol : water (100 : 13 : 17)v/v for papaya seed extract and methanol:chloroform (8:2)v/v for papaya stem extract. The results showed that ethanolic extract of papaya seed and stem have same antibacterial activity against Shigella dysenteriae and Streptococcus pyogenes. Based on TLC analysis, papaya seed contain alkaloid, steroid, and tannin, while papaya stem contain tannin.

Keywords: papaya (Carica papaya L.), antibacterial, Shigella dysenteriae, Streptococcus pyogenes.

INTRODUCTION

Papaya (Carica papaya L.) has many useful parts but not all of them are used. Seed and stem are usually discarded, though both of them contain a variety of compounds. Papaya seed contains alkaloid such as carpain, and glycosides such as glucotropaelin and benzyl-isothiocyanate (Nayak, 2012). Papaya stem contains alkaloid, tannin, saponin, steroid (Stephen et al., 2013) and anthraquinone (Setiawan, 2009).

and Escherichia coli with inhibition zone diameter of 13 and 17 mm, respectively (Okoye, 2011). Ethanolic extract of papaya stem with concentration of 0.5 g/mL inhibit Escherichia coli with inhibition zone diameter of 20 mm (Khan et al., 2014).

Active compounds in the seed and stem of papaya may solve the problem of resistance in the treatment of infections. The presence of infection in the body causes a variety of diseases (Tambayong, 2000). Shigella dysenteriae is a Gram-negative bacterium of genus Shigella that commonly causes gastrointestinal infection (Radji, 2009). Shigella

cause bloody mucoid diarrhea that is transmitted directly through food and drinking water (Sears et al., 2011). Diarrhea caused death of 5 million people each year, especially children (Shulman et al., 1994). Streptococcus pyogenes is a Gram-positive bacterium of genus Streptococcus that can spread infection by releasing a toxin. The bacteriacause skin, circulatory and respiratory system infections (Radji, 2009). This study was carried out to compare antibacterial activity of ethanolic extract of seed to stem extract of papaya (Carica papaya L.) against Shigella dysenteriae and Streptococcus pyogenes.

MATERIALS AND METHODS

Materials

Papaya seed and stem were obtained from Ringinsari, Randusari Village, District Teras, Boyolali, Shigella dysenteriae and Streptococcus pyogenes were obtained from Center of Health Laboratory of Yogyakarta, 70% ethanol, Mueller Hinton (MH) medium, Brain Heart Infussion (BHI), tetracycline, erythromycin, silica gel GF254, chloroform, methanol, ethyl acetate, distilled water, FeCl3, Dragendorff, ethanolic-KOH, Liebermann-Burchard (LB), and ammonia vapour.

Methods

Preparation of extract

White papaya seeds were taken from unripe papaya fruits which were about 2 to 5 months old. Papaya stem were taken from papaya trees that bear fruit. Briefly, 310 g of seed powder was extracted using 2.8 L 70% ethanol and 450 g of stem powder was extracted using 3.5 L of 70% ethanol in different maceration jar for 3-5 days and stirred manually every day. Papaya seed and stem extracts were filtered and concentrated using rotary evaporator and water bath.

(12)

Three or five pure colonies of Shigella dysenteriae and Streptococcus pyogenes

were touched with a sterile wire loop, suspended in 3 mL of Brain Heart Infussion and shook until reached the turbidity of McFarland’s standard.

Antibacterial activity test

Papaya seed and stem extracts were dissolved in 1.5 mL 70% ethanol to give a series concentration of 50%, 25%, 12.5%, and 6.25%. 20 µL of the extracts with concentrations of 50%, 25%, 12.5%, and 6.25% were loaded on sterile discs to give concentration of 10000 µg, 5000 µg, 2500 µg, and 1250 µg, respectively. Papaya seed and stem extracts were tested for antibacterial activity using the Kirby-Bauer disc diffusion method. Mueller Hinton agar plates were inoculated with 300 µL of Shigella dysenteriae

(1.5x108 CFU/mL) and 200 µL Streptococcus pyogenes (1.5x108 CFU/mL). After 20 min, 4 extract-loaded discs, 1 antibiotic disc (30 µg tetracycline disc as positive control for

Shigella dysenteriae and 30 µg erythromycin disc for Streptococcus pyogenes), and 1 70% ethanol-loaded disc (as a negative control) were transferred onto the agar surface of each plate using sterile forceps. The plates were then incubated at 37C for 24 hours. The activity of the papaya seed and stem extract as antibacterial against Shigella dysenteriae

and Streptococcus pyogenes was determined by measuring the diameter of inhibition zones.

Thin Layer Chromatography (TLC)

Chemical compounds in the papaya seed and stem extracts were identified using thin layer chromatography (TLC) with silica GF254 asstationary phase and a mobile phase of ethyl acetate:methanol:water (100:13:17) v/v for papaya seed extract and methanol:chloroform (8:2)v/v for papaya stem extract. 20 uL of extract solution with concentration of 50% were spotted on silica GF254 plates that had been activated by heating at 110C for 1 hour. When the sample has dried up, elution was carried out and the plate were removed when it reached the upper part of the silica plate. The spots on the silica plate were detected using visible light, UV 254 nm, 366 nm, ammonia vapour, and spray reagents such as FeCl3 Dragendorff, ethanolic- KOH, Liebermann-Burchard (LB).

(15)

Irradical zones with diameter of 7±0 mm were observed around discs containing papaya seed extract with concentration of 10000 µg and 5000 µg. It indicated that the seed extracts have antibacterial activity against Streptococcus pyogenes. Papaya seed extract at concentration of 2500 µg and 1250 µg did not have antibacterial activity against

Streptococcus pyogenes. Papaya stem extract at concentration of 10000 µg and 5000 µg gave inhibition zone with diameter of 7.33±0.57 and 7±0 mm, respectively. Papaya stem extract at concentration of 2500 µg and 1250 µg did not inhibit the growth of

Streptococcus pyogenes. Ethanolic extract of papaya seed and stem have same antibacterial activity against Streptococcus pyogenes. The ethanolic extract of papaya stem have inhibition zone of 28 mm while the papaya seed did not have inhibition zone against

Staphylococcus aureus (Khan et al., 2012). Based on the results of antibacterial tests against Streptococcus pyogenes, papaya stem extract inhibit Gram-positive bacteria better than papaya seed.

Thin Layer Chromatography (TLC)

TLC results showed that the ethanolic extract of papaya seed contains alkaloid, steroid, and tannin. Alkaloid was shown as brownish color with Rf value of 0.08 after it has been sprayed with Dragendorff. Steroid showed blue fluorescence under UV 366 nm with Rf values of 0.16 and 0.95 after being sprayed with LB. Tannin showed black colour with Rf value of 0.26 after it has been sprayed with FeCl3. TLC results showed that the ethanolic extract of papaya stem contains tannin. Tannin shows black colour after FeCl3 sprayed with Rf value of 0.53. In theory, steroid give a blue fluorescence after being sprayed with LB, alkaloids showed red orange yellow background gray, brown/orange brown after being sprayed with Dragendorff, and tannins show blue, red, purple, green, or black after spraying with FeCl3 (Wagner and Bladt, 1996).

CONCLUSION

The ethanolic extracts of papaya seed and stem have same antibacterial activity against Shigella dysenteriae and Streptococcus pyogenes. The ethanolic extract of papaya seed contains alkaloid, steroid, and tannin, while the ethanolic extract of papaya stem contains tannin.
